[Release] openai/openai-agents-python v0.10.3: v0.10.3

OpenAI Agents Python v0.10.3 release includes new features for exposing immutable agent tool invocation metadata on run results and adding RunResult tool_context accessor for agent tools. Performance improvements include using deque for BFS queue and voice task ordering, along with comprehensive documentation updates and test enhancements.

Key Points

• •Expose immutable agent tool invocation metadata on run results for better observability and debugging of tool calls
• •Add RunResult tool_context accessor to enable agent tools to access contextual information during execution
• •Optimize performance by replacing BFS queue implementation with deque and improving voice task ordering
• •Enhance documentation with nest_handoff_history parameter details and reorganized runtime guides for clarity
• •Improve test execution speed using xdist parallelization and deterministic waits for more reliable testing
• •Add MCP (Model Context Protocol) failure handling with tool_call_output_item emission for better error tracking
• •Update security and infrastructure dependencies (setup-uv, actions/stale) to latest versions
• •Maintain multi-language documentation with automated translation updates across all supported languages
